2 Claims.

The invention relates to a brush of a type suitable for applying a liquid finish or other substance to a floor or other surface.

The brush is in general provided with a cylindrical pad carried by a horizontal spindle, a yoke or frame connected to the spindle on each side of the brush, and a handle attached to the yoke or frame in a fixed position thereon.

The invention has as an object to provide the brush with a cylindrical pad which is restrained from rotation in normal use, but which is readily turnable on its axis to apply diierent parts thereof to the floor.

Another object is to provide a brush which is strong and durable and which may be readily and economically manufactured.

According to the invention from its fundamental aspect, the cylindrical pad is carried by an axial spindle connected at each end to the yoke and restrained from normal rotation, but readily turnable by exerting manual torque thereon.

According to the invention from another aspect, the brush is provided with a yoke or frame having a rigid cross-bar and a resilient side-bar at each end of the cross-bar to connect it to the spindle and thereby enable it to be readily removed from the pad.

The brush shown in the accompanying drawing and hereinafter described exemplifies and embodies the invention, and the views in the drawing are as follows:

Fig. l is a perspective view of the brush.

Fig. 2 is a side View.

Fig. 3 is a cross-section on the line 3-3 of Fig. 2.

Fig. 4 is a cross-section on the line 4-4 of Fig. 3.

Fig. 5 is a cross-section on the line 5 5 of Fig. 2.

The brush is provided with a cylindrical pad l connected by a yoke or frame 2 to a handle 3,

The cylindrical pad is formed by thrums or yarn bound between wires twisted together and forming an axial spindle 4.

The spindle at each end projects beyond the cylindrical pad to form a pintle.

The yoke is provided with a rigid cross-bar 5 and resilient side-bars 6 formed from a continuous flat metal strip bent transversely between the side-bars to give the cross-bar rigidity.

The side-bars each have formed therein a conical socket l to receive the pintles and thereby connect the brush to the yoke.

The conical socket forms at its bottom a seat 5 shaped to keep the pad from turning in being moved over the floor or other surface.

The cylindrical pad may be readily turned in the yoke by exerting manual torque thereon, as the side-bars will spread apart to release the pinfo tles from their seats in the sockets.

The yoke has attached to its cross-bar at the center thereof a tubular socket 3 to connect the handle 3 thereto.

The socket is formed of two semi-cylindrical l5 pieces for attachment to the handle, joined by a bight t looped around the cross-bar 5 and fastened thereto by a rivet I0.

A bolt il passes through the two halves of the socket 8 and through the handle to fasten the zo brush to the handle.

The invention which is described in the foregoing specication is susceptible of various changes and modifications which will embody the invention as defined by the hereinafter claims.

The invention embodied in the brush described in the foregoing speciiication and illustrated in the drawing is hereby dened and claimed as follows:

1. A brush, comprising a cylindrical pad formed by yarn and carried by an axial spindle, a yoke provided with a rigid cross-bar formed by a metal strip bent cross-wise to give it rigidity and with a resilient side-bar formed at each end of. said cross-bar from the same metal strip as said crossbar and having a recess formed in the outer end thereof to receive said spindle and the recess in one of said side-bars and the corresponding end of said pintle being shaped to keep said pad from turning in normal use but to allow said pad to be turned by manual torque being exerted thereon, a socket attached to said cross-bar at the center thereof, and a handle connected by said socket to said cross-bar.

2. A brush, comprising a cylindrical pad formed by yarn and carried by an axial spindle, a yoke provided with a rigid cross-bar formed by a metal strip bent cross-wise to give it rigidity and folded together at the center of said cross-bar and with a resilient side-bar formed at each end of said cross-bar from the same metal strip as said crossbar and having a recess formed in the outer end thereof to receive said spindle and the recess in one of said side-bars and the corresponding end of said spindle being shaped to keep said pad from turning in normal use but to allow said pad to be turned by manual torque being exerted thereon, a socket formed by a folded metal strip bent semi-cylindrical at each end and having its bight extending around the folded part of said cross-bar, and a handle connected to said socket by said cross-bar.
